Improved marine governor



UNITED STATES PATENT OFFICE.

HENRY J. BEHRENS, OF NEV YORK, N. Y.

IMPROVED MARINE GOVERNOR.

Specification forming part of Letters Patent No. 37,944, dated March 24, 1863.

.To all whom t may concern.:

Be it known that I, HENRY J. BEHRENs, of

, the city, county, and State of New York, have invented a new and Improved Marine Governor; and 1 do hereby declare that the following is a full, clear, und exact description of the saine, reference being had to 'the accompanying drawings, forming a part of this specilication, in which- Figure l represents a longitudinal vertical central section of my invention, the line a", Fig. 2, indicating the plane of section. Fig. 2 is a transverse vertical central section of the same, the plane ot' section being indicated by the lineyy, Fig. 1.

Similar letters of both views denote like parts.

The object of this invention is to make an ordinary pendulum or ball governor available for marine engines, and to arrange the same so that the rolling and pitching of the vessel has no disturbing inuence on the action of said governor.

The invention consists in combining with an ordinary pendulum or ball governor a universal joint or gimbal in such a manner that said governor will place itself always in a vertical position independent of the rolling or pitching motions ot' the ship. and that in consequence of this arrangement the action of the governor will be equally sure and correct in a rough and in a smooth sea.

The invention consists also in the arrangementof three bevel-wheels-onein the drivingshaft, one on one ot' the fulcrum-pins of the gimbal, and one on the top of the spindle of the governor-in such relation to each other and to .the giinbal from which the governor is suspended that the correct position of said wheels in relation to each other is not disturbed by the motions of the vessel and consequent oscillating motions of the governor and frames to which the wheels are attached.

The invention consists, further, in arranging the rising-and-falling rod within the spindle ofthe governor in such relation to the gimba-l that when the balls assume their mean position corresponding to the mean speed of the engine the top of said rod coincides with the common center of the gimbal, and, consequently, the motions of the vessel and consequent oscillating motions of the governor have no iniiuence onthe position of the throttlevalve.

The invention consists, finally, in placing the rod which transmits the motion of the balls to the valve loosely on the top of the risingand-falling rod, leaving the latter perfectly free to accommodate itself to the varying position ot' the vessel without disturbing its connection with said rod. 1

My invention will be perfectly understood by referring to the following description and v accompanying drawings.

A represents an ordinary pendulum-governor, the balls B of which are suspended from arms a, and these arms connect by links b with a sleeve, e, which is, placed loosely on the hollow spindle d. A pin, e, connects this sleeve to the rod f, which rises and falls in the hollow spindle d as the balls ily out or sink down, according to the quicker or slower motion of the engine. The spindle d of the governor is suspended in a frame, B, which is provided with two projecting arms, g, that hang on pivots h h. These pivots are firmly inserted into a frame, C, one opposite the other, and said frame is suspended at points opposite to each other and exactly between the pivots It h from a pivot, i', and from the drivingshaft j, the pivot t' being inserted into one end of a frame, D, and the shaft j having its bearing in the other end of said frame. This `frame is firmly bolted to some part of the engine or vessel and it supports the governor. The driving shaft j carries the bevel-wheel E, which gears into another bevel-wheel F, secured to the pivot h, from which the frame B is suspended, and through this bevel-wheel motion is imparted to a third bevel-wheel, G, secured to the top of the spindle d. lt will be noticed that when the frame D oscillates its center of oscillation coincides with the center of the bevel-wheel E, and consequently the wheel F will always remain inlgear with said wheel independent of the position of the frame D, and in the saine manner the frame B oscillates on a center which coincides with the center ot' the wheel F, and the oscilla-tions of said wheel, therefore, will not be able to disturb the correct position of the two wheels F and G in relation to each other; and the governorbeing suspended from the frames B G l), arranged like a gimbal, is at liberty to e A Y 37,944

place itself always in a vertical position, and.

it will, therefore,by its inherent gravity, main` tain its vertical position independent of the rolling and pitching of the vessel. It will act with equal correctness in a smooth and in a rough sea. The rod f,'which workswithin the hollow spindle d, is made of such a length that its top coincides with the universal center of the gimbal when the balls have assumed their.

normal position, and by these means the oscillations of the governor, caused by the rolling and pitching of the ship, have noodisturbing effect on the position of the throttle-valve. The motions oi' the rising-and-falling rod f are transmitted to the throttle-valve by' means of a rod, I, which rests loosely on the top ofl the rod f, being-depressed by `means of aweight or spring. Its lower end is iiattened kou/t so i that it oifers a broad bearing for-the top endy ofthe rod f, and that it is not liable'of being thrownl oii of said rod bythe motions of the tlefvalve will be just as sure in the roughest sea as vonfshore or on board a-ship in the calmest weather or inside a harbor.

What I claim as new, and desire -to secure by Letters Patent, is- 1. The combination, with an ordinary pendulum or ball governor, A, of a universal joint or gimbal, B G D, constructed substantially `as-herein-described, for the purpose setl forth.

'2; The arrangement of the three bevelywheels E rF G with the driving-shaft j, pivot l1., andspindle d, of the governor A, when the latter is suspended from a universal joint or gimbal, B G D, substantially as and for the purpose hereinshown and described.

' Se arranging-the rising-and-falling-rod f l with the governor A- and 'universaljoint or gimbal B C- D Ythat the top of saidf'rod'coincides with the-universalcenter ofthe gimbal when the-'balls of the governor assume -their mea-nposition,vsubstantially as andr for the purpose specified. l

4. Placing the rod I, which transmits `the motions ofthe balls to the throttle-valve,

loosely on lthe top ofthe rising-and-falling rod f, substantially as and for the `purpose specilied.
